Letters Patent No. 102,232, dated April 26, 1870.

' IMPROVEMENT IN MACHINE FOR MAKING WOODEN BOXES.

The Schedule referred to in these Letters Patent and making part of thesame. l

To all whom 'it may concern:

Beit knownthat I, JOHN GRONIN, of `Richmond, in the county of Henricoand State of Virginia, have invented a new and useful Machine for MakingWooden Boxes; andi do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings and to the letters of .reference marked thereon.

In the accompanying drawings- Figure l is a perspective view of mymachine.

Figure 2 is a plan of the same.

Figure 3 is an elevation, showing the gearing.

Figures 4. 5, and 6 are views of parts detached.

My invention consists of a machine provided with a carxiage'and clampfor holding boards in position for being nailed together in makingboxes, and, also, with a peculiar nail-feeder and a punch, a nail driverand two hammers, all operated automaticallyfor making boxes.

A sliding carriage A, traveling on ways B, is pro- Ivided with clampingsides C, which are adjustable by means of screws E in slotted arms D.

This carriage is moved by means of a crank-wheel, F, and paWl-arm G,which work ,in connection with ratchet-bar Y, fig. 5.

`This can-iage Amay be sixteen feet long,.or any other desired length,so as to receive four boards H, (a lready dressed to proper width,) andclamp the same for nailing them together, thus forming a long tube,which may afterward be out off in sections for separate boxes, 'and theend pieces inserted'and nailed.

The sides G of the carriage are adjusted to hold.

the side boards of the box while being nailed, and an adjustable roller,I, is employed to press home the covering board of the long tube or box.

The boards being thus clamped in place, a follower, V, iig. 4, alreadyinserted, serves as a gauge to regulate Athe size ofthe tubular box, andto helphold the boards until they are nailed, as follows:

A combined nail-feeder and driver is seen at K, figs. l and 6. The nailsZ, iig. 6, are fed into the-machine by hand, with the point downward.lwo slides, a and b, are Aso operated by springs d and e, and the punchor nail-driver L, that one nail drops at a time, and the nail-drivercornes down and drives the nail home into the box. As the nail-driverrises a second nail drops ready for the next stroke of the nail-driver,which is linked to the hammer M, and thus rises and falls with thehammer.

A punch, N, is employed to make a hole ready for the nail. This punch isdriven down by a hammer, O, and raised by a coiled spring, f.

'lhe hammers are operated by cams or snails P and Q,in connection withthe shafts It and S and the gear- A wheels 'l and U.

Any power-may be applied to the crank-wheel or hand-wheel WV. And Ipropose to duplicate the gearwheels, nail-feeder, punch, and hammers,'so as to nail both sides of the box or tube at one operation.

Having thus described my machine or invention, I claiml. The abovedescribed machine' for making wooden boxes, substantially as set forth.

2. The construction and arrangement of the nail- Afeeder K, providedwith the slides a b, 01 their equivalents, for forwarding a single nailat a time, substantially in the manner set forth.

3. The combination ofthe punch N, the nail-driver- L, and the hammers Oand M, substantially as de scribed.

4. The follower V, iig. 4, for gauging the size of the box while beingclamped and nailed, substantially as set forth.
